The essential property of a fertilizer is that is should be:
Correct answer: B. Highly soluble
- A. Immiscible
- B. Highly soluble
- C. Insoluble
- D. Partially soluble
Explanation
There are three essential plant nutrients for healthy growth: nitrogen (N), phosphorous (P), potassium (K). Fertilisers contain one or more of these nutrients and different crops require different proportions of each of the three. For the fertiliser to be effective, it must be soluble so that it can reach the plant's roots.

About Concentration Units
Concentration units express the amount of solute in a given amount of solution or solvent. Calculations cover molarity, molality, normality, mole fraction, mass percentage, volume percentage, parts per million and dilution, including the effect of temperature on volume-based units and the distinction between molarity and molality.
